How To Clean Engine Bay

Before you can degrease and clean the engine, it’s important to prepare it first. You can do that by giving it a quick pre-degreasing clean.

Remove the Debris From Your Engine Bay

Firstly, remove any debris that might be present in the engine bay. Whether there is grass, twigs, leaves, or paper, you should do your best to remove all debris as they can cause issues in the engine overtime.

Protect the Engine Electrical Components

Water can cause unfortunate damage to the electrical components and ultimately blow a fuse or two. However, there is a way to prevent this from happening. Simply, remove the battery from the engine and clean it separately outside. To do this, you’ll need to disconnect both of the battery terminals. Next, you’ll need to cover up all of the exposed wirings and components as well. To do this, wrap plastic around components such as the spark plug inlets and the distributor cap. Do the same for loose wires as well to make the components relatively waterproof.

Run the Engine to Help Engine Degreasing

It is easier to get rid of grease when the engine is heated, so keep the engine running for about five minutes or so to make the removal of any grease and grime easier.

Best Way to Degrease the Car Engine Bay

First things first, before you start to degrease your engine, always ensure you are wearing eye protection such as goggles, as well as making sure that you have covered all of the electrical components with a plastic cover.

So, once your engine is free of debris and warmed up, it’s time to actually carry out engine bay cleaning and degrease it. To do this, grab that handy degreaser spray, WD-40® Specialist® Fast Acting Degreaser Spray.

This fast-acting, solvent-based degreaser can effectively remove grease and grime from your engine without leaving residue. Cleaning and degreasing your engine will ensure that it runs smoothly and can ultimately prolong its life.

When applying the WD-40® Specialist® Fast Acting Degreaser, it’s important to avoid getting it onto the painted components, as it will remove the paint from the surface of your car. Always follow the manufacturer’s guidelines before using any products on your engine. However it is perfectly safe to degrease metal components and engine blocks.

Apply the WD-40® Specialist® Fast Acting Degreaser to the engine. The dirtier the engine, the more time you’ll need to leave the WD-40 formula on to allow it to work its magic. Most of the time, letting the formula sit on the engine for about three to five minutes should do the trick. Next, use a bristled brush to scrub it off and then rinse the engine with a hose afterward.

Washing the Car After Engine Bay Cleaning

While you’re at it, why not wash the entire car as well? Washing the car right after using an engine degreaser spray will ensure that any engine degreasing that might have found its way onto your car’s painted exterior is washed off immediately before it’s had a chance to do any real damage. Once you’ve washed it, why not finish the job off properly by following our guide on How To Wax & Polish Your Car By Hand.

How to Clean the Car Engine Components

After you’ve degreased the engine, we highly recommend you clean the individual parts as well. For example, cleaning the terminals of your car battery (or any other plastic surfaces within your vehicle) with a wire or bristled brush is an important factor and process when participating in an engine deep clean. Remember, your car will only stay in good condition if you maintain it and clean it properly.

Always remember to follow the manufacturer’s guidelines.
